The main purpose of the device is the detection of packet (pulsed) radio signals and radio transmitting devices of all modern communication systems. High scanning speed compared to other versions of ARINST analyzers is achieved through the use of two frequency synthesizers. For advanced analysis, functions for displaying the time-frequency spectrum "waterfall chart" and "digital phosphorus" have been added. They are designed to observe the evolution of signals in both the frequency and time domains.

It enables service centers and maintenance teams to perform on-the-spot HF analysis for commissioning and repair works. Moreover, the spectrum analyzer is a perfect solution for repair workshops and radio amateurs.

Principle of operation

The spectrum analyzer is a portable device that is connected to the measured circuit and has an independent power supply. The device has a 3.2" color resistive touch screen to display the signal spectrum and to control the device.

All measured data are displayed on the device screen in the real time.
